Question

Consider the following data set: 5, 10, 24, 79, 103 If you were told to determine the mean which formula is most appropriate to use? What other formula could you use, although it is less desirable? What would you have to keep in mind if you used this second formula?

Answer 1

See below

Explanation:

To determine the mean (average) for the data set 5, 10, 24, 79, 103:

The most appropriate formula is the arithmetic mean formula, which calculates the mean by summing all values and dividing by the number of values. In this case:

Mean = (5 + 10 + 24 + 79 + 103) / 5 = 44.2

The less desirable formula would be the weighted mean formula, but it's unnecessary for this dataset since all values are treated equally. If you were to use the weighted mean formula, you'd need to assign appropriate weights to each value, which is not needed here. Therefore, the arithmetic mean formula is simpler and suitable for this dataset.

Answer 2

see explanation

Explanation:

the mean is calculated as

sum of data ÷ count ( number of values in data set ) , that is

mean =
`(sum)/(count)`
